Thus, those of ordinary skill in the art should realize that various changes and modifications can be made to the embodiments described here without departing from the scope and spirit of the present disclosure. Likewise, descriptions of well-known functions and structures are omitted in the following description for clarity and conciseness.

An embodiment of the present disclosure firstly provides an annotation tool generation method, and as shown in FIG. 1, the annotation tool generation method may include:

S11: acquiring a first function module generated based on a first language, wherein the first function module is configured for acquiring a file to be annotated;

S12: acquiring a second function module generated based on a second language;

S13: converting the second function module into a third function module in a webpage-oriented binary format, wherein the third function module is configured for presenting the file to be annotated on an annotation page and displaying an annotation result corresponding to the file to be annotated on the annotation page; and

S14: generating an annotation tool based on the first function module and the third function module.

According to the embodiment of the present disclosure, the annotation module written in the second language is translated into a core annotation module in a webpage-oriented binary format, so that the language translation can be performed by utilizing a mature annotation algorithm, and meanwhile, the specific content of the mature annotation algorithm can be protected.

In the embodiment, the first function module may be a business logic module, for acquiring a file to be annotated from a server side. The third function module may be a core annotation module, for presenting the file to be annotated and the annotation information on the annotation page, and acquiring the annotation result by the annotation page.

The second function module generated in the second language may be an annotation module contained in a known algorithm library, or may be a non-known annotation module.

In this embodiment, the acquiring the first function module generated based on the first language may specifically include: generating the first function module, according to a writing operation in the first language input by an operator.

The acquiring the first function module generated based on the first language may specifically include: generating the first function module, according to an operation that the operator calls a program template edited in the first language in advance and an editing operation to the program template in the first language.

In this embodiment, the first language may be different from the second language. For example, the first language may be a common computer language, and the second language may be a more specialized computer language. The second language may be a language in which web pages are less compatible, and the first language may be a language in which web pages are more compatible.

In the embodiment, the first function module may be written in JavaScript, and may be configured for:

acquiring an annotation task from a server through an Hyper Text Transmit Protocol (HTTP) and downloading a file to be annotated;

sending, to a core annotation module, an instruction for loading a point cloud, via an interface with the core annotation module;

obtaining a current annotation result from the core annotation module via the interface with the core annotation module, wherein the current annotation result includes annotation information such as a size, a position, a direction, an attribute and the like of each annotation box;

submitting the current annotation result to a server side through the HTTP protocol, after an operator finishes the annotation to the file to be annotated; and

receiving a callback of the core annotation module, to enable the first function module to display a 2D auxiliary image and a projection box on the annotation page.

In this embodiment, the third function module may be written using C++, compiled into WebAssembly for use by a Web browser. In one implementation, the third function module may include a structure shown in FIG. 3:

OpenGL (Open Graphic Library) compatibility layer 31: the desktop OpenGL API (OpenGL Application Programming Interface) may be translated into WebGL (Web Graphic Library), and the C++ part may be developed directly using OpenGL.

Picture element layer 32: each picture element in the annotation picture is abstracted, and each picture element is organized in a tree-shaped manner Picture elements include point clouds, cubes (annotation boxes), spheres, cylinders, etc. The picture elements may be organized as shown in FIG. 4. Meanwhile, the drawing operation of the picture elements is performed by the OpenGL interface, to realize the drawing of various individual picture elements.

Rendering window component 33: the rendering function of the annotation picture as a whole is realized, and the annotation elements organized in a tree form are called in a depth-first traversal mode, to render the whole picture. Meanwhile, events such as a mouse operation, a window size change and the like of a keyboard of a user are received through a Simple DirectMedia Layer (SDL) library, and the events are sent to other components of the core annotation module.

Task management component 34: an external interface is provided to a business logic module, wherein the external interface includes loading a point cloud, outputting an annotation result and the like.

Annotation box creation and adjustment component 35: an annotation box is created and adjusted according to the instructions of creating a box, adjusting the size of the box, adjusting the position of the box, adjusting the attribute of the box and the like received from the user, and the annotation box is stored in the picture element layer. In a case where the annotation box is created and adjusted, PCL (Point Cloud Library), a mature algorithm library in the industry such as Eigen (a linear arithmetic C++ template library) and the like may be used to achieve some intelligent functions improving the efficiency of user annotation.

An operator may call the interface of the core annotation module by clicking buttons such as building a new box, adjusting the box and the like on the annotation page of the browser, to send a corresponding instruction to the core annotation module.

In this embodiment, the second function module written in the second language is translated into a third function module in a webpage-oriented binary format, so that the language translation can be performed by utilizing a mature annotation algorithm, and meanwhile, specific codes of the mature annotation algorithm can be protected.

In one implementation, an annotation tool generation method may further include:

Alternatively, the graphic interface in the open graphic library format is input into a translation module, and translated into the graphic interface in the webpage graphic library format.

In this embodiment, the standard adopted by the graphic interface in the webpage graphic library format can be compatible with the webpage and the third function module written in the second language and converted into the webpage-oriented binary format, so that information transmission can be performed between the annotation page at the front end and the third function module.

In this embodiment, the graphic interface in the open graphic library format is translated into the graphic interface in the webpage graphic library format, so that the third function module can perform information interaction with the front-end webpage via the interface, and detect the event generated by the annotation operation.

In one implementation, the first language is JavaScript, and the second language is C++.

For the C++ language development, the user interface is more complex, and development cost is higher, but the intellectual property protection function is stronger. JavaScript source codes may be obtained directly from a browser, and may be roughly understood even after confusion. It has poor confidentiality and is not conducive to protecting specific code content, but the code is simple and easy to write.

In this embodiment, the first language is JavaScript, so that the part with low confidentiality requirement is written in a simple and changeable language, the code writing difficulty is reduced, and the portability of the annotation tool is improved; and the second language is C++, so that the mature algorithm of C++ may be utilized, and the specific content of the mature algorithm is protected, making it hard to be stolen.
